Does any one know if leave it charged is bad for the battery, or not? :?:

I read somewhere that li-ion batteries work better when charged often. It's to do with the way the batteries degrade. Mine is generally on charge more often than not and I have noticed no loss of life in nearly a year.

I do wish I could find a way to bypass that 72 hour rule though.

What 72 hrs rule?

The battery only drains to about 50% to allow for 72 hours main battery backup in case you are away from a charger for the weekend or something.

As I'm never away from a charging source for more than 2 hours, I want to disable this to allow extra usage at any one time.

Hope I answered your question earlier.

From reading Li-Ion behavior over the internet, they said while Li-Ion battery provides a light weight, it is sensitive on the overcharging issue.

So, I was concern in overcharging mine.
But, perhaps the charger has a built-in mechanism to sense full charge and prevents overcharge the battery. :?

In any way, thank you for your input on charging the batter and the 72 hrs rule.

Some essential information on Li-Ion batteries:

Contrary to popular belief, Li-Ion batteries DON'T have a memory effect like NiMh or NiCads do, you don't have to charge them for 10/12 hours when you first get them, you just give them a topup charge to make sure they're full and off you go.

Whenever I get back home, and I'm at my PC or in my room, I'll always charge my phone in. The XDA literally eats battery life, and I'm seriously debating buying one of those 2600mAh batteries to replace the supplied one, it sucks if you're using it for anything like Bluetooth and you're not using an in-car charger / you're walking around in a town or city for a fair while.
